Question

When do creative people get their best ideas? USA Today did a survey of 966 inventors (who hold U.S. patents) and obtained the following information.

(a) Assuming that the time interval includes the left limit and all the times up to but not including the right limit, estimate the probability that an inventor has a best idea during each time interval: from 6 A.M. to 12 noon, from 12 noon to 6 P.M., from 6 P.M. to 12 midnight, from 12 midnight to 6 A.M. (Enter your answers to 3 decimal places.)

(b) Do the probabilities add up to 1? (Choose one of the options:)

No, because they do not cover the entire sample space.

Yes, because they cover the entire sample space.

Yes, because they do not cover the entire sample space.

No, because they cover the entire sample space.

(c). What is the sample space in this problem? Choose one of the options:

12AM-12PM

6AM-6PM

6AM-12AM

The entire day
